This was a great place to stay in the heart of Bangkok. The duplex is exactly like it looks on the listing. This was my family's first experience using Airbnb and it was exactly what we hoped for. (I often think good reviews are written by someone with a connection to the host - not true in my case). Here is why I would recommend it to future travelers.
Very clean, stylish unit 25 stories up.
In the heart of Bangkok next to many 5-star hotels where you get a comparable room without paying 5 times a much. The unit also includes a doorman in the lobby who always greets you with a cheerful greeting, opens the entry doors, and even pushes the button to call the elevator down as you are entering the building. The lobby staff also helped us get our family's luggage to our room, and had a taxi waiting for us when we departed at 4:00 am in the morning.
It is across the street from the train to anywhere in Bangkok, just a 5 minute ride to heart of shopping district (or 10 minute walk), and there is a small modern convenience store a 100 meters from the building entry that has most of what you need.
I called Erik a few times on the phone as we were arriving and he was very responsive on helping us get situated. He really cares that you are happy with his unit.
